Contrary to popular belief, Andalucian is not a dialect of Spanish, but his is very confusing. There is something called Andalusian Spanish. This is what the announcer in this video is speaking.
I can understand Spanish pretty well, but this guy is almost incomprehensible, and this is just a mere dialect. I showed it to two friends who have some Spanish comprehension as most White native Californians do. One thought it was Romanian and the other thought it was Italian. If you understand Spanish, Romanian, Portuguese or any Romance language, see how much of this Andalucian you can get.
However, there is more to the story. In the vignettes in this video, you will see people speaking something altogether different, not a dialect of Spanish, but a full-blown separate language altogether, Andalucian. True, it is not recognized by Ethnologue yet, but it ought to be. Part of the problem is Spanish fascist nationalism that will not tolerate any more languages in Spain.
So far, Catalan, Basque, Occitan and Galician are recognized, but many others, such as Extremaduran, Asturian, Asturian, Fala, Portuguese, Aragonese and Leonese are not. Andalucian is another one, in this case not even recognized as a language by the ISO yet.
Andalucian has a heavy Arabic influence and in particular an influence for Mozarabic, which is an extinct form of heavily Arabized Spanish.
